Combination warm and cool mist humidifier

humidifier comprising:

• a housing;
• a main water reservoir within the housing open to atmospheric pressure that is finable by providing water through an opening in a top portion of the housing;
• an engine deck disposed within the housing and configured to hold water, the engine deck being disposed above a bottom of the main water reservoir;
• a water feature disposed above the main water reservoir and configured to direct water to an overflow chamber of the engine deck;
• an impeller configured to pump water from the main water reservoir to the water feature;
• an engine chamber disposed adjacent the main water reservoir and below the engine deck, the engine chamber including at least one motor for driving the impeller and a fan, the fan being configured to generate an air flow over the engine deck and out of the housing;
• and
• a humidification device disposed on the engine deck and configured to dissipate water into the air flow.

A humidifier comprising:

• a housing;
• a main water reservoir within the housing open to atmospheric pressure that is finable by providing water to an opening in a top portion of the housing;
• a fan configured to generate an air flow through the housing;
• an impeller configured to pump water toward a top of the humidifier;

A humidifier comprising:

• a housing;
• a main water reservoir within the housing open to atmospheric pressure that is tillable by providing water through an opening in a top portion of the housing;
• a fan configured to generate an air flow through the housing;
• a wicking filter disposed above the main water reservoir and configured to distribute water into the air flow, the wicking filter being substantially planar and inclined from which excess water drips in a controlled manner into a conduit;
• an impeller configured to pump water to a water feature disposed above the main water reservoir, the water feature configured to drip a portion of the pumped water onto the wicking filter and to direct at least a portion of the pumped water back to the main water reservoir, the water feature including a downward curved slope and a funnel at a bottom of the slope;
• and
• at east one motor for driving the impeller and the fan.

A humidifier comprising:

• a housing;
• a main water reservoir within the housing open to atmospheric pressure that is fillable by providing water through an opening in a top portion of the housing;
• a fan configured to generate an air flow through the housing;
• a wicking filter disposed above the main reservoir and configured to distribute water into the air flow;
• an impeller configured to pump water to a water feature disposed above the main water reservoir, the water feature configured to drip a portion of the pumped water onto the wicking filter and to direct at least a portion of the pumped water back to the main water reservoir, the water feature including a channel and at least one divider defining first and second conduits within the channel, wherein the first conduit is disposed below the second conduit such that a flow of water below a threshold volume flows only through the first conduit while a flow of water above the threshold volume flows through the first and second channel;
• and
• at least one motor for driving the impeller and the fan.
